st: Paramertric survival analysis: shared frailty

I conducting a survival analysis and wish to model hospital-level
effects. Using "stcox", there is an option to estimate the random
effects "effect(nu)", however this option is not allowed with the
"streg" command for parametric survival analysis. I wish to know if
there is an option equivalent to "effects(nu)" that can be used with
"streg", or alternatively how else I can get an estimate the random
effects?
